Ok. If I converted would I be able to add ac? That would help with hauling my newborn. And what gauges would I be able to eliminate?
Yes, you could install the A/C compressor in place of the second alternator without significant mods. Adding A/C does seem like a fair piece of work, though. Might be a better idea to trade for a truck that comes with A/C and 12V already installed.

Gauges aren't required, you can eliminate any of the ones that bother you. But if you remove the second alternator to fit the compressor, you won't be needing the "GEN 2" light anymore.
